307 engine

Or how about the satisfaction of being able to say that he was able to make a 307 have some decent power??

I don't like the 307 for personal ($) reasons, but it would be nice to see one haul *ss. I think if he works on getting the car under 2500 lbs. it could potentially be a nice setup.... fiberglass, aluminum, and lexan everything. The engine does pull nicely at low rpms. But to seriously build it up would compromise the whole aesthetics of the 307, it'd then make power at higher rpms.

This one makes 327 torque at 2500 rpms. That would be great for a street engine. http://popularhotrodding.automotive.com ... tions.html

The bottom line is that it is possible to make power with these engines, you just have to know you are doing.

To the original poster, since you are not stuck on just a 307, I think a 330 would be a good choice also for being unique. You would be able to get more power and those engines can rev a lot higher. They also already have a forged crank and solid mains.

That's impressive, 430 tq at 4600-4700 rpm. It doesn't seem like it would take kindly to high revs...I have a feeling it's meant just for a dyno queen. The lift on the cam is pretty stout, and how much tuning went into that 800 cfm carb?!

i've read all the responses. i know it woud be very espensive to build the 307. and we're so going have to agree to disgree on this subject when i first wrote tis subject i didn't it would get this far. i just build a 307 because i haven't seen one that hauls a**. as for 330 0r 425 to rebuild and put in the car i would love to build for some hp but i can't find one in my aera. belive me i looked everywhere to find an olds v8 engine.

Im no master mechanic nor do I claim to be but an engine is an air pump and they are all the same in principle,forced induction or NA.NA makes the power with air FLOWING thru ports,FI makes it by FORCING air thru the ports.Only someone who had no clue about forced induction engines would make a statement that theyre not the same thing at all.....Please explain to me what bit of evidence youve ever seen that backs up what you think.

The engines are the same basic designs, but a forced induction engine uses completely a different theory to build power and make them last. Someone that knows how to build a N/A engine will probably not know how to make power out of a forced induction engine, same thing the other way around. They need different cams, fuel systems, compression ratios, exhaust, etc.

finally somebody that get's it!!

Does it have to be olds powered? I mean, if you don't care about having the original engine, I don't understand why you want to go in uncharted territory. As engines go, you've got thousands of templates and examples on the internet, magazines, etc. Just take something that has been proven to work and put down the numbers and make it your own.

It just doesn't make sense, it's like a ricer mentality applied to an engine instead of a body kit. Spend 4-6 grand and make a damn nice SBC or 455 olds.

This is what I was saying with the 1st post to him. This guy wants to throw/waste thousands of dollars at a dead horse. Apparently he has more money that what he knows what to do with & wants to try & prove a point.

The only point he will achieve is a muti thousand dollar, 300 horse polished turd that's will still get a beat down by bone stock 'Stangs.

I'm still getting troll vibes here though. :?

Hey, I give this guy credit. He definatly deserves it. I was considering this, but I couldn't do it to my factory motor. So I might as well get a bigger motor if I have to get another motor anyway. I still have some wet dreams about a twin turbo'd 307. I mean, J&S makes a full halo girdle for it, and with a stock rebuild they have something like 7.8:1 compression. So they could handle some boost, stay together, and make some real power.
Now yes they'll need a ton of headwork still, maybe custom pistons to lower the cr some more, a custom cam, one hell of a fuel delivery system, and DEEP pockets, but it would be fun wiping the floor with gn's in a 307 car!!!

I have a friend who was real big into Olds racing dating back to the 70's. In the 80's he ran an 81 Cutlass which was sponsored by Olds from 82-90 or so. Then he went to a Firechicken and then an Achevia. He always ran a 307 due to his class he ran. He would be pushing 600 plus HP outta that little thing. I dont kno wwhat all he did to them but I know he would bore them out to equal a 350 .60 over and sleeve the cylinders. He won and set several IHRA records thru the yrs. So yes if you prep it right the 307 will run good! Just my .02's

That's the point, it took all that to get it to make huge power.
Hell I'm giving up on my 307, it's a good putz around engine, has alittle bit of balls. But I'm gunna try to find a 455, rebuild that, put a decent cam and an intake on it and a 200 shot and just be done with it. I only wanna be quick on the street, fast on the strip. BB with juice will do that just fine.

No they do not.

You guys think a turbo or SC is some majic vodoo when it is not...

Then again,im arguing with some fools that think a 307 is even worth building.
